Jrheelareer .w tie spf thel-eham ert I is d si ned riot-serve asa-a compartment for dry. ru

3 bish which usually consists mainly of paper and readily combustible material and a basket for wet garbage is provided by two curved grills or reticulated walls which are spaced apart and are supported in the combustion chamber H. The front wall or grill it of the garbage compartment is of a forwardly convex curved form approximating a portion of an inverted cone and extending entirely across the chamber H at its upper portion but taperin downwardly to a narrow terminal which is carried by a supporting lug l! riveted to the wall 5 at some distance from the bottom I, this distance approximating the height of the clean-out door M at the opposite side of the chamber I l. The rear wall H! of the garbage compartment is also in the form of a grill and may be shaped approximately as a portion of a cone of smaller radius than the front wall l6 so as to provide a space between the two grills It and I8 to receive the garbage to be dried and consumed inthe incinerator. At the lower end the wall I8 tapers almost to a point and rests directly upon the supporting lug ll, being formed with a hook or shoulder IQ for interengagement with a downwardly projecting lug on the lower end surface of the front wall l6, as seen in Fig. 5. An upstanding guard flange 2| of the supporting lug I! retains the lower end of the grill H8 in position while the interengagement of the hook l9 and lug 20 serve to hold the front wall or grill IS in position at its lower end. At the upper end the front wall rests against abutment lugs 22 which are cast integral with, and project downwardly from, the top ring I; and the upper end of the back wall [8 includes lugs 23 from which bolts 24 extend through the top ring 1.

At the rear of the structure the ring I includes a segmental portion I having an opening 25 which serves as the smoke outlet for the incinerator and which is surrounded by a flange 26 for connection with a smoke pipe indicated in dotted lines at 26 in Fig. 2. Adjacent the straight edge 21 of the area l this top casting includes squared openings 28 to receive the rounded hinge lugs 29 of the cover 30 which completes the closure of the upper end of the incinerator and rests upon the inner marginal portion of the ring 1 when in closed position, as shown in Fig. 1. An arm 3| projects from the forward edge of the cover 3!! and is provided with a coiled wire handle 32 of the heat radiating type by which the cover may be swung upwardly for access tothe dry rubbish and garbage compartments of the structure. A latch or brace arm 33 is pivotally hung from the under side of the cover at 34 in position to ride over and rest upon an upwardly grooved lug 35 which projects inwardly from the ring 1 so that the latch arm 33 serves as a prop to hold the cover in raised position, as shown in Fig, 2, while the waste material is being placed in the incinerator. As shown in Fig. 7, the latch arm 33 is bent with a lateral offset at 33 so that the upper end portion adjacent the pivot at 34 is spaced fromthe plane of the lower end which engages the grooved lug 35. To release the latch it is only necessary to push the cover 30' upwardly a little beyond the position shown in Fig. 2, thus allowing the latch to swing clear of the lug 35 into a vertically pendant position, as shown in dotted lines; then as the cover is lowered the latch will ride downwardly against the rear face of the lug until the offset 33 passes below the lug, allowing the latch to swing forward into position to ride over the front face of the lug 35 when the cover is again raised. This makes it possible to raise or lower the cover with one hand and without touching the latch 33 which is likely to be coated with soot as a result of its position in the incinerator during the burning of material therein. The single cover 39 provides access both to the dry rubbish compartment in the chamber II and to the garbage compartment formed between the grills l6 and Ill. The latch mechanism is the subject of a divisional application Serial No. 607,876, filed July 30, 1945.

When there is sufiicient accumulation of material in the incinerator the dry rubbish may be 7 lighted with a match near the top and the cover will be closed, but combustion will be temporarily sustained by air entering the inlet ports l2 and reaching the upper portion of the chamber ll through a supplemental air port 36 in the front portion of the wall 5. As combustion proceeds, however, the principal portion of the air entering the jacket space 6 through the ports IE will flow downwardly in the jacket and will enter the chamber H through the opening it, it being understood, of course, that the door M is normally kept closed. To prevent the opening (3 from becoming clogged with refuse and rubbish in the chamber H a bafile or deflector plate 31 of the form shown in dotted outline in Fig. 4 extends from the inner surface of the wall 5 as a hood over the space adjacent the door M, as indicated in Fig. 5. It will be evident that, if desired, the door l4 may be momentarily opened and a match may be applied to the material in the lower portion of the chamber II.

As combustion proceeds and the smoke and hot gases pass through the openings of the grills l5 and I8 and through the wet garbage held between them so as to escape through the smoke outlet 25, and the air which is drawn in through the ports I2 is rapidly heated as it flows downi wardly through the annular jacket space 6 and degrees F. Any excess of this heated air which is not required to support combustion flows with the products of combustion through the grills l6 and I8 and assists in the drying of the Wet material until this material is in condition to burn i: also. To insure this result in the event that the garbage compartment is not entirely filled, the upper portion of the wall I8 is formed as shown at 38, without openings, so as to serve as a baffle adjacent the smoke outlet 25 which prevents the products of combustion in the upper portion of the chamber H from reaching the smoke outlet without first passing through the reticulated portion of the wall l8 and through the wet garbage held in this lower portion of the basket.

For simplicity and economy of construction the incinerator is made in a generally cylindrical form requiring no special bending or forming of the side walls 4 and 5; and it will be noted that the assembly of the parts thus becomes an extremely simple matter, which consists mainly of the placing of the side walls between the bottom wall I and the top ring I and securing the tie bolts it which hold these parts together. The hinge lugs 29 of the cover are not fastened in place but merely fit loosely into the openings 23 into which they swing when the cover is raised; the rear grill [8 of the garbage basket is readily placed in position and secured by the two bolts 2 24, while the front grill I6 is simply lodged in its position of use and can be quickly removed,

if desired. 'Irr'is found u'nnec'es'sary to provide a bottomi grate in a structure of this character, and "practically tllhiateiial bums-to a fine light ash which can 7 be -"ea si-ly removed tlirough the clean -out door'- I 4.
